ADVERBIAL CLAUSES
INTRODUCTION

Definition
They modify a verb (either finite or non-finite), an
adjective, an adverb or another clause.
e.g.:
Don’t start before the machine is ready for operation
Functioning until the transmission was completed, the
link provided an optimum performance
The portable was simpler than it was expected
The programmer worked harder than he ever did before
As it turned out, the satellite did not fulfil safety
requirements
ADVERBIAL CLAUSES
INTRODUCTION (2)

Position
Most commonly, at the beginning or the end of the
main clause. In some cases, medial position.
e.g. :
If possible, use a different method
The scene must be illuminated until a
distinctive image appears
I was told that, if I applied early, I would
be given an immediate answer
ADVERBIAL CLAUSES

Classification of adverbial clauses
The exact number of adverbial clauses is open to doubt,
since meanings sometimes overlap and the same clause may
express different semantic values. The meaning intended by
the clause can be deduced either from the introducing
conjunction or from the sentence as a whole.
Here, we shall consider the most common types, and more
precisely, those that appear more often in technical texts.
ADVERBIAL CLAUSES

CLAUSES OF TIME
They answer the question “When?” and are common
in the initial or end position.
Main conjunctions: WHEN, WHENEVER,
BEFORE, AFTER, UNTIL, SINCE, ONCE, AS,
NOW THAT, AS SOON AS, AS LONG AS, THE
MOMENT, DIRECTLY, WHILE.
Some of these conjunctions may introduce verbless
or abbreviated time clauses.
ADVERBIAL CLAUSES
e.g.:
When the line is engaged, the hold-on mode is automatically
assigned
Signals were modified as they entered the first multiplexor
Directly the data arrived at its destination, the user interface
transformed the flow into intelligible information
Now that the research connected with the
telecommunications field is advancing so fast, work
prospects are also increasing
When in doubt, ask for information (verbless)
Once finished, disconnect the equipment (abbreviated)
ADVERBIAL CLAUSES

CLAUSES OF PLACE
They answer the question “Where?”.
Conjunctions (also for verbless and
abbreviated clauses): WHERE, WHEREVER
e.g.:
Answer “yes” or “no” where appropriate
Wherever possible, all parts should be
tested
ADVERBIAL CLAUSES

CLAUSES OF CONDITION
These clauses give the circumstances under which the
statement of the main clause will take place or be true, i.e.,
they state the dependence of one circumstance or set of
circumstances on another.
Main conjunctions: IF (positive cond.), UNLESS (negative
cond.), PROVIDED THAT, PROVIDING, SUPPOSED,
SUPPOSING (mostly connected with questions), SO LONG
AS, AS LONG AS, SO THAT, ON CONDITION THAT.
ADVERBIAL CLAUSES
e.g.:
If the international line is engaged, you must replace the
handset and try again
Unless it works properly, results will be unreliable (If it
doesn’t work properly, results...)
Supposing the teacher saw you cheating, what would you do?
You will be given the prize provided (that) your project is a
novelty
The director will phone you on condition that you make an
appointment previously
(Notice that the “comma” is compulsory whenever the
subordinate comes first)
ADVERBIAL CLAUSES

Real and unreal conditions
Real: We are not sure whether the condition has been (will
be) fulfilled or not.
Unreal: It is clear the condition has not been fulfilled (though
it could be)
e.g.:
If it works, it will be a success (Real)
If it worked, I didn’t realise (Real. Simple past in both
clauses. Clearly factual)
If it worked, it would be a success (Unreal. Conditional in the
main clause. Hypothetical.)
If it had worked, I would have realised (Unreal. Impossible)
ADVERBIAL CLAUSES
Clauses beginning with “If” are similar to
questions which imply uncertainty. Thus, they
tend to contain non-assertive forms such as
“Ever” and “Any”.
Clauses beginning with “Unless” stress the
“excluded positive option” and, so, they
normally contain assertive forms like “Some”.
For the same reason, these clauses are not
usually unreal conditions.
ADVERBIAL CLAUSES
e.g.:
If you ever hear any news from the company, let me know
Don’t call me unless you’ve got something new to tell me
If we hadn’t upgraded the system, we would have had a
lot of problems (unreal condition). *Unless we had
upgraded ...
Both “If” and “Unless” can introduce abbreviated and
verbless clauses.
e.g.:
If ready, let’s begin
The lab is closed on Saturday unless otherwise stated
ADVERBIAL CLAUSES

Special types of conditional clauses
1. Present subjunctive used in legal English: “If he be found guilty, he will
be punished”
2. WAS TO or WERE TO followed by the infinitive: “If it was/were to
work, that would be a success”
3. SHOULD followed by the infinitive: “If a crisis should arise, the
company would have to close for good”
4. The conjunction is omitted and the auxiliaries SHOULD, WERE or
HAD introduce the subordinate: “Should you finish on time, let me know”.
“Were he to call, tell him I’m out”. “Had the project been finished on time,
the network would have been operative without undesirable delays”
5. An infinitive clause can also be used conditionally: To do a thing like
that, you must be stupid”
ADVERBIAL CLAUSES

Indirect conditions
They behave as STYLE DISJUNCTS (Quite useful for oral presentations)
a. Conventional expressions of politeness. Speaker’s
utterance seemingly dependent on the permission of the
hearer:
If you don’t mind my saying so, you’ve made a mistake
If I may be quite frank with you, you’ve made a mistake
Other expressions: “If I may say so”, “If I may be personal”,
“If we can be practical for a moment”, “If I may put the
matter as simple as possible”, “If I may interrupt”, “If I may
change the subject”.
ADVERBIAL CLAUSES
b. Calls for the hearer’s agreement, suggesting that
the wording is not quite precise or that he should
not be misunderstood:
The Big Bang theory of the origin of the Universe
bears a startling resemblance to the description of
creation in Genesis, if one may put it so.
Other expressions: “If that is the correct term”, “If
that is the word for it”, “If you see what I mean”,
“If you like”.
ADVERBIAL CLAUSES
c. To express either speaker’s or hearer’s
uncertainty:
Chomsky’s views cannot be reconciled with Piaget’s
if I understand both correctly
Other expressions: “If I’m correct”, “In case you
don’t remember” (Ironical: “Einstein’s theory of
gravitation is based on a mathematical concept, in
case you don’t remember/in case you have already
forgotten”), “If you know what I’m referring to”.
ADVERBIAL CLAUSES
CLAUSES OF CONCESSION



Closely associated to conditionals, except that they imply a
contrast between two circumstances.
Principal conjunctions: (AL)THOUGH, EVEN THOUGH,
EVEN IF, WHILE, WHEREAS.
‘Although’ as a subordinator is approximately the equivalent
of ‘but’ as a co-ordinator. The conjunction EVEN IF implies
an overlap between conditional and concessive clauses.
WHILE and WHEREAS often point to a contrast between
comparable things.
ADVERBIAL CLAUSES


e.g.:
We will do our best, although we are not keen.
You will enjoy this program, even if you dislike
computers.
Whereas services haven’t been paid their due
attention, the impact of technology is constantly in
the news.
PCs are used everywhere, while Macs are mainly
restricted to the office environment.
ADVERBIAL CLAUSES



Though generally the conjunction IF is conditional,
it can be used concessively: ‘If cable TV is gaining
adepts, it doesn’t seem to’.
Very often, the conjunction follows the
complement: ‘Successful, though it was, the
connection only lasted a few seconds’.
Abbreviated clauses of concession are common
with verbless or participle constructions: ‘Though a
bit obsolete, we are still working with a Pentium II
processor’. ‘Though infected, the program didn’t
cause any damage’.
ADVERBIAL CLAUSES

Conditional-concessive clauses
1. Alternative conditional-concessive: They give a choice
between two possible conditions.. Introduced by the
correlative conjunction WHETHER......OR.
2. Universal conditional-concessive: Generally introduced
by some WH- word or expression (whatever, whoever, no
matter wh-...). They can also begin with certain fixed
expressions:
Come what may (whatever may happen)
Do what you will (whatever you do)
Be that as it may (however that may be)

input, the system always takes its time to process
that.

in advance.
ADVERBIAL CLAUSES
CLAUSES OF REASON OR CAUSE





They give the reason for the activity expressed in the
main clause.
Main conjunctions: BECAUSE, SINCE, AS...
Whereas is sometimes used to introduce a clause of
reason in legal English.
Conjunctions typically associated with time can also
introduce these clauses.
In many cases, the conjunction is omitted.
ADVERBIAL CLAUSES
e.g.:
It is true because I say it is.
Whereas the defendant has pleaded guilty, the Court
will be lenient with him.
We’ll have to rearrange the configuration after we
said we would.
Being a man of ingenuity, he repaired the machine.
We are happy you can manage.
ADVERBIAL CLAUSES
CLAUSES OF PURPOSE

They state the finality of the action expressed by the main verb. Mainly
introduced by: IN ORDER THAT/TO, IN ORDER FOR (+ noun), SO
(THAT), SO AS TO... Very often they occur in the form of a full infinitive
(as it happened with conditionals).

e.g.:
The program was scanned so that unknown viruses could be found.
We left the device connected in order for the staff to access relevant
information whenever required.
He destroyed the papers so that no one might see them.
To open the carcass, you have to press down the button.
ADVERBIAL CLAUSES
CLAUSES OF RESULT



They state what has happened (or may happen) as the result of the action
or state expressed by the main clause.
Principal conjunctions: SO.....THAT, SO (THAT), SUCH.....THAT,
SUCH (THAT).
e.g.:
We introduced the necessary changes so that the operations gave the
expected result.
Our finances are such that we cannot afford another increase in the
production expenses.
Sometimes, clauses of result are similar to clauses of purpose. Compare:
‘We rearranged the configuration so that it could work properly’ with ‘. . .
so that it worked properly’.
ADVERBIAL CLAUSES
CLAUSES OF COMPARISON

They answer the questions HOW MUCH?, HOW LITTLE?. The
principal conjunctions are AS, AS THOUGH/IF, AS.....AS, SO.....AS
and structures of comparison. If there is doubt or unreality, the past
tense is used. Sometimes, an inversion subject/verb is produced.

e.g.:
Mathematicians often behave as though they knew all the answers.
This is not a bad result as prices go.
The composite is as dry as it’s going to get.
Our company created new branches abroad, as did our competitors.
ADVERBIAL CLAUSES
CLAUSES OF PROPORTION AND PREFERENCE
 Clauses of proportion express a proportionality or
equivalence of tendency or degree between situations. They
are introduced by AS or the correlatives THE.....THE (with a
‘fake’ comparative structure).
 Clauses of preference are introduced by RATHER THAN or
SOONER THAN followed by a bare infinitive. RATHER
THAN can also precede a gerund or a noun.
ADVERBIAL CLAUSES

e.g.:
As speed increased, more losses were produced.
The more we thought about the matter, the less we
understood it.
Rather/Sooner than reducing the capacity, I’d
replace several components.
Rather than bulky deflecting coils, we’ll employ an
electrostatic focus.
ADVERBIAL CLAUSES
REVERSAL OF WORD ORDER AFTER ADVERBIAL ELEMENTS
The usual order Subject + Verb is reversed after the following adverbial
elements:
1. Adverbial elements of negation: NO, NOT, NEVER, NEITHER.
e.g.: ‘In no case can an exception be made’
‘Never had I seen such an outstanding performance’
2. Negative conjunctions: NOT ONLY.....BUT, NO SOONER.....THAN.
e.g.: ‘Not only is it very efficient but it’s quite inexpensive too’
‘No sooner had we begun our presentation than the light went off’
3. Adverbial elements of near (quasi) negation: SCARCELY,
SELDOM, RARELY, BARELY, HARDLY.
e.g.: ‘Seldom has anyone succeeded in this business’

REVERSAL OF WORD ORDER AFTER ADVERBIAL ELEMENTS(2)
4. Adverbial elements including ‘only’: ‘Only after the 1992 agreement
on borderless trade, is the haze beginning to clear around the concept of
the Common Market of Communications’
5. Adverbial elements including ‘so’, and also after ‘so’ as a
conjunction: ‘So critical did detecting the first failure become that
designers decided to choose a redundant configuration’
‘The constant rise in productivity is hardly attributable to human effort
only, and so is the globalisation of the market’
6. Adverbial elements of place: ‘Inside the room lay scattered the basic
elements employed for propulsion, sensing and control. Among them was
the latest microprocessor’
